"a? 12 I I! 2??? n L 10 1 1 135 I 29 "Q V 1Z fi/ imlmnmmm actualpractice, is from thirty to forty-"five feet in length, it would be alaborious proc ess to shift the individual needles in or out, and toobviate this I provide the bar 31,

.which has a plurality of regularly spaced transversely therethe rail10, are driven through the bar so that their unheaded ends will projectfrom the corresponding face of. the bar. The bar is then appliedto theblocks 14:,with the said. projecting ends of the screws 32 within narrowgrooves 34 of the blocks, and moved,

bodily, in a direction toward the outer edge of the rail 10, with theresult that the de-' sired needles are projected from the rail, intooperativeposition. -l 'he other screws 38 are properly adjusted, in thesame man-- ner as the screws 32, but at different intervals, so thatother groups, or needle blocks, at corresponding intervals, may be movedin; or out. By thisarrangement, it is possible to project the needles atthe desired intervals for producing the stitching necessary for theembroidered. design. This is clearly shown in Figures 4 and 5, theformer showing the bar in operative position, while the latter shows thebar in fragmentary perspective view. A

By this construction, when it is desired to use certain needles anddiscontinue the use of the remainder thereof, those which are not to beused are positively held in such position as to offer no interference.

3V hat is claimed is:

1. An embroidering machine needle device including a main block having aplurality of transverse grooves in one face,'

needle holding blocks slidable grooves and each havmg a groove in itsupper face, "the main block having a longi tudinal groove in its upperface intersecting in said the transverse grooves, and a locking bar"slidable in the longitudinal groove and havmg projections "on its lowerface for engagement in the grooves of-the needle blocks to hold theblocks against movement in the:

transverse grooves.

2. An embroidering machine needle" =de{ vice including a main blockhaving a plurality of transverse grooves in one face and a longitudinalgroove in its upper face ad jacent one edge thereof and a longitudinalopening ad acent the opposite edge',sa1'd longitudinal grooveand-opening intersecting the transverse grooves, a needle block slidablein each of the transverse grooves and having transverse grooves in itsupper and lower faces adjacent its opposite ends respectively andadaptedfor alignment with the longitudinal groove and opening respectively, alocking barslidable in'the lon gitudinal groove and having transversepas sages in itslower face resulting in intermediate projections the.latter being ar ranged to enter the upper grooves of the needle blocks,and'a locking bar slid-able inrsaid opening and havingtransversepassages resulting in intermediate projections arranged to enter the,lower transverse grooves of the needle blocks.

In testimony whereof, I affix my signa-
